Can we use "sequencer" field in bucket notification to determine the sequence of events in a MinIO cluster

Hi team, I have a few questions about the sequencer field in bucket notifications. I see in MinIO bucket notifications documentation that it is similar to S3 event notifications, and in S3 event message structure that "The sequencer key provides a way to determine the sequence of events.". I see in the code that sequencer field in bucket notification is generated based on current timestamp. I'm wondering can we use it to determine the sequence of events in a MinIO cluster?

There is no sequence synchronization, so no.

Thank you for the clarification!

Another quick follow up question - can we use "sequencer" field to determine order of events for the same object? My understanding is no but wanted to double check.
